VEHICLE BUMPER.

Application filed November 80, 1923. Serial no.

To all whom it may concern:

Be it known that I, Lnorn BLAcnMoRa, a citizen of the United States, anda resident of Highland Park, county of Wayne, and State of Michigan,have invented certain new and useful Improvements in Vehicle Bumpers, ofwhichthe following is a full, clear, concise, and exact description,such as will enable others skilled in the art to which the inventionrelates to make and use the same, reference being made therein to theaccompanying drawings which form a part of this specification.

This invention relates to safety devices, and is illustrated as embodiedin a motor vehicle having a front bumper.

An object of the invention is to provide a double-bar spring bumper witha support of maximum strength and resilience, preferably' by spacing theimpact bars from a spring supporting bar by means of a spacing deviceslidably engaging the impact bars.

This and other objects and features of the invention, including variousnovel combinations of parts and desirable particular constructions, willbe apparent from the following description of the illustrativeembodiment shown in the accompanying drawings, in which Fig. 1 is a topplan view of the front end of an automobile having a bumper asdescribed; 1 i

I Fig. 2 is a front elevation of the bumper;

Fig. 3 is a vertical section on the line 33 of. Fig. 1, showing thespacing device; and Fig. 4: is a view corresponding to Fig. '1,

' but showing a modification.

In the arrangement selected for illustra- .tion, the invention isembodied in an automobile havin a radiator 10, a chassis frame includingsidef members 12 and a cross member 14;, and side fenders 16. In orderto protect the radiator and fenders, a front bumper of novel form isprovided.

In the modification shown in Figs. 1-3, the bumper comprisesvertically-spaced impact bars 18 and 20, having eyes at opposite endsembracing shackle bolts which connect them to horizontally-aimedsupporting bars 22 and 24 arrange opposite the space between the bars 18and 20. A bracket 26 is bolted-or otherwise secured to each of the bars22 and 24 and to the corresponding side frame member 12. As shown inFigs. 1 and era rec 8, the supporting bars 22 and 24 are forwardlyflanged at their adjacent ends, and are secured by a bolt or otherwiseto a member 28 forming part of a spacing device, and which is formed atits front end as an eye or sleeve between bars 18 and 20. A bolt 30 heldby this eye draws hook-shaped clamping members 32v against the top ofbar 18 and the bottom of bar 20, providing a sliding, engagement withthese bars.

The modification shown in Fig. 4: differs from the one described abovein that a single supporting bar 34 is substituted for bars .22 and 24,and an L-shaped member 36 bolted to its center is substituted for member28. 1 I

In both modifications it will be seen that each supporting bar is bowedrearwardly at the point where it is secured to the frame, and is spacedat the center of the'bumper a substantial distance from the impact'bars,by a rigid connection 28 or 36 which engages va forwardly-bowed portionof the supporting bar or bars. This gives in effect the strength andresilience of an elliptic spring to all parts of the bumper.

While particular desirable embodiments of the invention have beendescribed in detail, it is not my intention to limit its scope to thoseembodiments, or otherwise than by the terms of the appended claims.

I claim: a 1. A vehicle having a chassis frame and a bumper, the bumpercomprising, in combination, a pair of vertically-spaced parallel vtransverse spring impact bars, a spring suptransverse spring impactbars, a spring supporting bar consisting of a pair of alined. springsupporting bars having opposite ends arranged between and connected tothe corresponding ends of the impact bars, means for attaching thesupporting bar to the chassis frame, and a spacing device securedbetween the adjacent ends of the suppetting ezi'tendiing a snhstantiaidistance fetvve'id and sheiahiy engaging the impact having a pair ofciam'ps siidahiy engaging the impact hats a Avehiele having a chassisframe and a hnmpei", the bumper comprising in combination,vertically-spaced impact bars, a continneus supporting hat secured atits opposite ends to the impact hairs and carried by the chassis frame,and a spacing tievice secured tn the snpnerting hat and having a pain atclamps siidiahiy engaging the its pact hats 50 A vehicle having achassis trams and hnmpen the bumper eemprising in combinatien, a pair ofverticaiiy-spaced parallel transverse spring impact bars, a spring supporting" means heiizentaiiy spaced between the en s cf the impact hatsand carried by the chassis frame, and a spacing device securedt to thecenter of the spring support ing means and extending a substantial distance fervvai'dt siidahly engaging the'impact hats In testimony whereofI afitix my signature.
